COVERING FOR HYfiRANT-PIPES.

srncIFIcAT'IoN forming part of Letters Patent No. 616,127, dated December cc, 1898.

Application filed February 15, 1898. Serial No. 670,361. (No model.)

To ctZZ whom it may concern:

Be it known that I, MARIE H. MERGENTHA- LER, a citizen of the United States, residing at Albany, in the county of Albany and State of New York, have invented'new and useful Improvements in Coverings for Pipes for Supplying Water to Hydrants, Hopper-Closets, &c., of which the following is a specification.

My invention relates to coverings for Waterpipes of hydrants, hopper-closets, and other devices to which Water is to be supplied in cold weather; and it consists of the novel fea tures, elements, and combinations and arran gements of parts and elements hereinafter described, and pointed out in the claims.

The objects of my invention are, first, to provide for water-pipes for hydrants, hopperclosets, and other devices coverings which will protect the same from cold or freezing in winter; second, to provide the pipes for supplying water to such devices with longitudinal sections which will comprise wall-sections which will maintain their shapei. 6., textile-fabric walls which are non-absorbent of water and interior non-conducting substance through which neither heat nor cold will pass, and, finally, to provide with longitudinal sectional coverings comprising each walls which are non-absorbents of water, walls which are adapted to retain their original form and shape, and interior non conducting substance, devices adapted to securely hold the said longitudinal sectional coverings in place Fig. is a section taken at line 2 2 in Fig. 3.

The same letters of reference refer to similar parts throughout the several views.

In the drawings, A, Figs. 1 and 2, is a firehydrant supply-pipe, which pipe may be of Fig. 1 is a plan view of the same, and,

'any suitable form of construction and provided with usual interior valve-chamber, valve, and adjuncts for operating the same, and the discharge member a for connection with fire-hose for service, and is provided with a suitable outer jacket A, which may be of metal or wood, as is generally provided for protection, all of which devices and parts are so well known as not to require any particular description. This pipe A is made with such a length downward from its discharge end as may be required for place of the valve-chamber a at a point below the surface of the ground, to which the frost cannot reach in coldest weather. A Figs. 3, 4, and 5, is a supply water-pipe for a hoppercloset, which pipe is suitably connected by its discharge end with the hopper-bowl A and is provided with a suitable cock 0. by

means of which the water-supply may be cut off at will from discharging into the said bowl. This hopper-bowl,with its supply-pipe and cock, is so Well known that itrequires no particular description.

B is my improved pipe-covering, which is sectional in character in its longitudinal direction and may comprise two or more longitudinal sections, as illustrated in Figs. 2 and 5. These sections, (marked B B,) whether two or more in number, for inclosing the pipe A or A are made in cross area on segments of circles corresponding with that required in their assemblage for nicely inclosin g the same, as illustrated in Figs. 2 and 5. Each of these sections B, in any group of two, three, or more are preferably made each substantially the same as the other in proportions of parts-say as halves, thirds, quarters, or other fractional forms-as may be preferred or may be found to be advantageous for use or convenience for readily covering the article to be protected from freezing. These sections B B of the covering B are shown on large scale in Figs. 1 and 2 and comprise each a stiff case 0, a non-absorbent outer textile case D, and a non-conductor filling material E, closely packed within said case 0. The walls 0 c c 0 (shown in Figs. 1 and 2 by full lines) of said inner stiff case may be made of any suitable stiff material which is adapted to retain its original form and shape when the section B it forms a part of is completed for use and may be made of sheet metal, as iron or zinc, or of hard campact paper-board sized and stiffened by resin and properly shaped and connected or secured together, so as to produce a stiff-walled case in which the inner concave wall 0, outer convex wall 0, and side edge walls 0 0 when properly connected or secured, may cooperate to keep the case in original curvature.

The walls of the outer case D, comprising walls 61 d d (1 are made of suitable textile fabric, as, say, duck-canvas, of suitable thickness, well saturated with asuitable non-absorbent substance which will resist the passage of water through these walls. For cheapness as a substance, facility of saturation when heated, hardness when cold, effectiveness for resisting the passage of water through the walls of the case, and endurance in use I preferably saturate the material of said walls cl cl (1 d of this outer case with a nonabsorbent or water-resisting composition composed of resin and tallow, which may be used together in proportion of one-third, by weight, of the former to two-thirds of the latter, melted together and thoroughlyincorporated with each other and applied and pressed into the fabric of said walls when heated. This proportion of the said two substances may be varied without materially changing the water resisting quality of the composition. .Vhen this covering is to terminate in the ground or liable to have its lower end submerged at times in water, I form with each case 0 and D of each sectional covering B a bottom, as e (indicated by dotted lines in Fig. 1,) and suitably connected with the respective walls a c c c of case 0, and a bottom, as (1, (indicated by dotted lines in the same figure,) suitably connected with walls d d d d of case D, which bottoms c d of the respective cases are preferably made of materials like those of the walls they are joined to, with the bottom d of the outer textile case D made to be a non-absorbent of water, the same as its side walls. These bottom walls 0 (Z operate to prevent water entering into either of said cases of the respective sections 13 and gradually rise and become absorbed bycapillary attraction in the non-conducting filling material E and wetting the same. Although the non-conducting filling material E of these sections B of this pipe-covering may be of any suitable substance which is a good non-conductor of refrigeratory chills from the outer side walls to the inner side walls of the respective sections, yet I use as my preferred substance for a non-conductor filling material ashes of coal, preferably anthracite, uniformly granulated and drypacked within each case 0 of each cover-section B of this pipe-covering. These granulated coal-ashes are found by me to be a nonconductor of high order of refrigeratory chills and adapted to naturally pack uniformly within the cases of the sections and to be both comparatively light in weight and not liable to readily shift within the cases inc1osing the same and not adapted to operate when in bulk to bulge outwardly and deflect from original shapes any of the walls of the cases within which these ashes are held. This material E is filled into the respective cases of the sections to theirfull lengths of extension and are then closed over by suitable top wallpieces (1 of non-absorbent material, with or without a top wall-piece cfiwhich mayin some cases be omitted, especially when a cap-form end-covering cap F, Figs. 1, 3, and 4:, is applied. WVhen these sectional coverings B B are assembled about the water-supply pipe or device, as illustrated in Figs. 2 and 5,with

the surfaces of their adjoining side edges bearing against each other, as shown, there will be applied to the outer sides of these assembled sections suitable binding devices or bands at suit-able distances apart, which devices I prefer to make of copper wire e e, of suitable size and proportionate to the size of the sections employed, tightly wound around and secured at their ends by twisting, as illustrated in Fig. 1.

For preventing the refrigeratory chill from freezing atmosphere from passing into the water-supply device through the walls of its head or other end I provide an end-closing cap F, Figs. 1, 3, and 4, which may be seetional in its form of construction, as illustrated by full and dotted lines in Fig. 4. This end-closing capis made of the same material, preferably, as that employed in the cases of the sectional coverings B B and, like the latter, comprises two casesf and f, the former of 'stifi material and the latter of textile material and made to be a non-absorbent of wa ter by saturation with a water-resisting composition similar to that described as being preferably applied to the material of the walls of case D of the sectional covering B. The chambers of cap F are filled with the granulated ashes, as a non-conducting filling ma terial E. The sections of the covering-cap F are securely and tightly bound together by suitable bands 6 6, preferably of copper wire and secured similar to binding-wires e e of the assembled sections B B. These end-covering caps F may fit over the end portions of the assembled sectional coverings B B as do the telescopic form of cover shown by full lines in Fig. 1, or the inner side walls of the side portions of thecap may be made in the form of an annular bevel or incline, as indicated by dotted lines at f Fig. 1, and in correspondence with an annular bevel or incline given to the upper end of the covering 13, as indicated by dotted lines at 1), same figure. When this covering 13 is to be applied to pipes having a length thereof at an angle to another length, as pipes A A in Fig. 3, the joined coverings B B will be made with suitable beveljoint at 22 when a suitable flexible or other bandage B preferably of strong textile material and saturated with the water-resisting compound employed for saturating the ma terial of the walls of the cases D of the sectional coverings B, so that this corner or bevel joint bandage may be adapted to exclude water from entrance to said joint.

I have omit-ted from Figs. 3 and 4 the binding devices shown at e and e in Fig. 1 for tightly securing the assembled sectional coverings B B, yet it is to be understood that such binding devices are to be employed, and as illustrated in Fig. 5 at e Having described my invention, what I claim, and desire to secure by Letters Patent, 1s-

1. For use for covering water-supply devices, a longitudinal section-cover B formed by the combination with an inner case 0 of stiff material and made withv a form corresponding with the wall portion of the watersupply device it is to be applied to, and an outer walled case D of textile material which is a non-absorbent of water and inclosing said case 0, of the non-conducting filling material E described packed in the case 0, and having both ends closed by either wall 0 or d or both, substantially as and for the purposes set forth.

2. The sectional covering B, for water-supply devices, formed by the combination of two or more longitudinal section-covers B B comprising the inner case 0, having its Walls of stiff material, and an outer case D of textile material which is adapted to resist the passage of water, and incloses the said inner case, and the granulated non-conducting material E of coal-ashes filling said inner case, the. said sections adapted to be bound together when assembled about the water-sup.- ply' device by bands, substantially as and for the purposes set forth.
